* Postscreen: Give temporary whitelist status to primary MX addresses only.Guilhem Moulin2016-09-201
|
* systemd: Ensure sympa service is enabled.Guilhem Moulin2016-09-181
|
* lacme-certs.conf: don't restart but reload dovecot after renewing IMAPS cert.Guilhem Moulin2016-09-181
| | | | | | Unfortunately as of Debian 8.6 (Jessie) dovecot's service file doesn't have a “Reload” directive, so we can't use `/bin/systemctl restart dovecot` as notification. It'll be fixed in Stretch, though.
* Postfix: ensure common aliases are present.Guilhem Moulin2016-09-183
|
* FreshClam: change ownership of /etc/clamav/freshclam.conf.Guilhem Moulin2016-09-181
| | | | | | | | To match the stock version shipped by clamav-freshclam 0.99.2+dfsg-0+deb8u2 ~$ stat -c '%U:%G %a' /etc/clamav/freshclam.conf clamav:adm 444
* Firewall: allow duplicates rules.Guilhem Moulin2016-09-181
|
* More logcheck-database tweaks.Guilhem Moulin2016-08-222
|
* HSTS: use the standard capitalization of includeSubDomains.Guilhem Moulin2016-07-121
| | | | Cf. RFC 6797 sec. 6.1.2.
* postfix: Remove obsolete templates tls_policy/relay_clientcerts.Guilhem Moulin2016-07-124
|
* postfix: commit the master.cf symlinks.Guilhem Moulin2016-07-125
|
* nginx: Don't hard-code the HPKP headers.Guilhem Moulin2016-07-1213
| | | | | Instead, lookup the pubkeys and compute the digests on the fly. But never modify the actual header snippet to avoid locking our users out.
* Postfix lists/MDA instances: only include the MX:es' IPs in $mynetworks.Guilhem Moulin2016-07-102
|
* Route all internal SMTP traffic through IPsec.Guilhem Moulin2016-07-1013
|
* Postfix MX/MSA instances: put certs in the the instance's $config_directory.Guilhem Moulin2016-07-105
|
* Postfix MX/MSA instances: don't ask the remote SMTP client for a client ↵Guilhem Moulin2016-07-102
| | | | | | | certificate. See postconf(5). This avoids the “(Client did not present a certificate)” messages in the Received headers.
* Postfix: avoid hardcoding the instance names.Guilhem Moulin2016-07-102
|
* Postfix: don't share the master.cf between the instances.Guilhem Moulin2016-07-1012
|
* postfix: Don't explicitly set inet_interfaces=all as it's the default.Guilhem Moulin2016-07-105
|
* Change the pubkey extension from .pem to .pub.Guilhem Moulin2016-07-107
|
* Route SMTP traffic from the webmail through IPsec.Guilhem Moulin2016-07-108
|
* More logcheck-database tweaks.Guilhem Moulin2016-07-092
|
* Localize the NTP pool hostnames.Guilhem Moulin2016-07-091
|
* Localize the debian archive hostnames.Guilhem Moulin2016-07-091
|
* ClamAV (FreshClam): use a localized Database Mirror.Guilhem Moulin2016-07-092
| | | | | | As db.local.clamav.net is not always properly localized. Furthermore, our previous Ansiblee script did not ensure ordering of the DatabaseMirror lines.
* IMAP: don't include mailbox under the virtual namespace in LIST responses.Guilhem Moulin2016-07-062
| | | | | | | | | Clients now have to use the NAMESPACE extension [RFC 2342] to discover mailboxes under the “virtual/” namespace. (Plus an extra LIST command, causing an overhead two roundtrips.) Of course the downside is that non namespace-aware clients lose access to the “virtual/{all,flagged,…}” mailboxes, but on second thought it's probably better this way rather than having such clients treat these mailboxes as regular mailboxes.
* dovecot: use the MSA postfix instance for sieve redirection.Guilhem Moulin2016-07-012
| | | | | We don't want to use the default instance since its SIZE limit is tighter than the ones on the MX:es.
* IPSec → IPsecGuilhem Moulin2016-06-295
|
* More logcheck-database tweaks.Guilhem Moulin2016-06-293
|
* update-firewall.sh: COMMIT empty iptables rule files.Guilhem Moulin2016-06-291
|
* Postfix MSA: don't allow unauthenticated clients from $mynetworks.Guilhem Moulin2016-06-291
|
* certs/public: fetch each cert's pubkey (SPKI), not the cert itself.Guilhem Moulin2016-06-157
| | | | To avoid new commits upon cert renewal.
* Rename letsencrypt-tiny to lacme.Guilhem Moulin2016-06-157
|
* wwsympa systemd service file: Set PrivateTmp=yes.Guilhem Moulin2016-06-071
| | | | The CGI wants to create a temp file during bulk subcription.
* clamav: Don't set obsolete option 'AllowSupplementaryGroups'.Guilhem Moulin2016-06-051
|
* Use stunnel to secure the connection from the webmail to ldap.fripost.org.Guilhem Moulin2016-06-055
| | | | | We should use IPSec instead, but doing so would force us to weaken slapd.conf's ‘security’ setting.
* postfix: rotate the sender address for verify probes.Guilhem Moulin2016-06-022
| | | | | In order to avoid ‘double-bounce@’ ending up on spammer mailing lists. See http://www.postfix.org/ADDRESS_VERIFICATION_README.html .
* Remove the IMAP caching proxy.Guilhem Moulin2016-05-2810
| | | | | | | | | Dovecot imapc requires two authentication rounds to the IMAP backend for each connection. It seems suboptimal that Roundcube keeps connecting to the IMAP server for each new connection, but benchmarks shows little advantage in caching the IMAP sessions with imapproxy: http://www.dovecot.org/list/dovecot/2012-February/133544.html
* Roundcube: route IMAP and managesieve traffic through IPSec.Guilhem Moulin2016-05-282
